Elon Musk has vowed to begin launching one million AI data center satellites into orbit in 2028, via the still experimental Starship rocket, in a high-risk plan that could trigger a financial catastrophe, and send SpaceX into a high-speed nosedive.

But a cascade of delays in demoing the Starship in orbit caused them to reopen the lunar landing competition, and SpaceX is now facing off against Blue Origin<\/u> in a race to complete a lunar touchdown spacecraft by 2028.<\/p>\n SpaceX\u2019s chief designer prophesied in his Web-posted missive that: \u201cThe capabilities we unlock by making space-based data centers a reality will fund and enable self-growing bases on the Moon, an entire civilization on Mars and ultimately expansion to the Universe.\u201d<\/p>\n Dr. Zubrin told me SpaceX has led a revolution in the design of reusable spacecraft with its Falcon 9 rocket.<\/p>\n SpaceX is now the global superpower in terms of total rocket launches, with an average of three lift-offs per week in 2025, more than NASA or any other government space agency.<\/p>\n But to skyrocket from that flight cadence to one launch every hour, or 8700 flights every year, with the still unproven Starship by 2028 is unimaginable.<\/p>\n Likewise, Zubrin says, \u201cLaunching a million satellite orbital data center constellation is fantasy.\u201d<\/p>\n Dr. Zubrin is not only at the global forefront in aeronautical engineering, but also founded the Mars Society, a planet-spanning think tank and design studio to promote terraforming and colonizing the Red Planet. <\/p>\n He has known Elon Musk for a quarter century, since Musk made a contribution to the Society and was briefly named to its board of directors, before he founded SpaceX with the goal of speeding the first human explorers to the Martian dunes. <\/p>\n Since then, Zubrin has been a de facto mentor to Musk, trumpeting his spaceflight triumphs and his goal of creating the first hyper-tech cosmopolis on Mars<\/u>, but also warning against strategic missteps that could jeopardize that quest, like the new quixotic, out-of-the-blue scheme to rocket generative AI agents to circle the Earth.<\/p>\n The American space seer says he wrote an appeal to Musk, published in a magazine article, to caution him against the cosmic boondoggle of constructing a mega-cluster of space-based data centers that could not compete economically with terrestrial counterparts.<\/p>\n To an outside observer, especially neophytes to the spaceflight sector, Musk\u2019s masterplan for the super-constellation might seem like a logical progression after he assembled the rings of Starlink satellites that now transmit internet connections to 10 million people across the face of the Earth.<\/p>\n SpaceX\u2019s master architect, Zubrin writes in the appeal<\/u><\/a>, \u201ctakes things step by step, with each step providing the ample financial basis that enables the next.\u201d <\/p>\n \u201cHe helped create PayPal, which gave him the funds to launch SpaceX.\u201d <\/p>\n \u201cThe SpaceX Falcon 9 became a money maker, which enabled him to launch Starlink.\u201d <\/p>\n \u201cStarlink has not only made him even richer, it has made him far more powerful than any other businessman on Earth.\u201d<\/p>\n SpaceX’s Starlink satellites have not only helped skyrocket Elon Musk across the pantheon of space tycoons, but also have “made him far more powerful than any other businessman on Earth.\u201d (Photo by: Alan Dyer\/VW Pics\/Universal Images Group via Getty Images)<\/span><\/p>\n VW Pics\/Universal Images Group via Getty Images<\/small><\/div>\n<\/div>\n<\/figure>\n But the new scheme to build sensationally costly and colossal bands of AI satellites, Zubrin adds, could lead to SpaceX\u2019s financial crash and burn. <\/p>\n Musk proposes powering these super-armadas of satellites with solar panels. <\/p>\n But Zubrin, echoing a host of other eminent space scholars, says that now, and for the foreseeable future, \u201cspace solar power is vastly more expensive than solar power on Earth, and even that is not fully competitive with fossil fuels, hydro, or nuclear.\u201d <\/p>\n The solar panels on each SpaceX Starlink satellite generate 20 kilowatts of electric power. The $2,000,000 price tag on each of these spacecraft means one kilowatt of power costs $100,000, Zubrin says.<\/p>\n In contrast, he adds, solar arrays positioned on rooftops scattered across the planet produce electricity that costs about $3000 per kilowatt, while power from gas-fired generators costs roughly $1000 per kilowatt.<\/p>\n Zubrin, who holds a doctorate degree in nuclear engineering, says commercial nuclear power plants produce power at $5000 to $10,000 per kilowatt.<\/p>\n Any of these terrestrial power options, he points out, would be far cheaper than the solar wings that Elon Musk has proposed to fly his AI spacecraft.<\/p>\n While the Starlink satellites have to be sent into orbit to beam internet connections to users across the continents, Zubrin says, there is no comparable need to send AI data centers into space, especially one that would justify the sky-high price tag on each spacecraft. <\/p>\n Brian Hurley, founder of the influential New Space Economy think tank and digital magazine, told me in an interview that top researchers worldwide on the potential launch of orbital data centers customized to host AI models have reached a consensus that these stations will not become economically feasible until the mid-2030s.<\/p>\n
